Title: Timing relay driven by sync. motor - has series diode switched in to disable motor when set time expires
Inventor: PFAFF HERBERT
IPC: H01H43/10
Filed: 1978-02-23
Abstract: The timing relay has a sync. motor rotating a timing disc against the action of a return spring. The disc operates the relay's contacts when the preset time has elapsed and disables the motor. A diode(D) is connected in series with the motor (M) and is shorted out by a switch whilst the preset time is running. This switch is opened by a cam on the disc when the time expires. The diode may be in series with a resistor and the resulting combination shorted by the switch. The motor may be shunted by a capacitor.

Title: Dyeing synthetic hydrophobic fibres with organophilic dye - by extn. process using aq. liquor contg. emulsifier
Inventor: KRUCKENBERG WINFRIED DR
IPC: D06P1/00
Filed: 1978-07-14
Abstract: To dye synthetic, hydrophobic fibre materials with organophilic dyestuffs free from SO3H gps., an aq. liquor contg. emulsifier and circulating in a circuit is passed through a dyestuff depot from which the dyestuff is abstracted by a process of dissolution and is then fed to the material to be dyed. Fibres which can be dyed are polyesters, cellulose, acetate and polyamides, and their blends with each other or with natural fibres such as wool or cotton. Compared with the process of DT 1938792 or 2215336 (in which an organic solvent is used), the present process can be run without the use of special dye formulations (prepd. by expensive grinding processes) and with the observance of economically interesting dyeing times. Also the process is not tied to particular preconditions as regards appts.

Title: Aluminium press mould for boneless ham - coated internally by spraying epoxy! resin antistick layer
Inventor: BLASER EDUARD
IPC: A22C7/00
Filed: 1978-11-06
Abstract: A press mould for boneless ham consists of an upper and a lower part, made of Al or an Al alloy. The inside surfaces are shotblasted, treated in chromic acid, and are sprayed with a thermosetting plastic to a thickness of 6-8 mu.

Title: Absorption of thermal radiation, esp. solar energy - which is collected by circulating aq. soln. of nickel salt, so efficient heat absorption is achieved
Inventor: HERRMANN HERBERT
IPC: C09K5/08
Filed: 1979-06-06
Abstract: The energy passes through the transparent or translucent wall of a container or pipe in which is an aq. soln. of a Ni salt used as a heat absorption liq.; and the wall of the pipe or container is at least permeable to infrared rays. The pref. soln. contains NiCl2 or NiSO4, and esp. 4 kg. of either salt mixed with 5 l. water, and at pH 5-7. One pref. plant uses a coil of heat-resistant, transparent plastic pipe, through which the soln. is circulated via a pump and then flows through a heat exchanger. The rear wall of the pipe coil is pref. provided with thermal insulation. The inventor has discovered that Ni salt solns. are exceptionally efficient when used to absorb heat.
Patent DE-2923967-A1 (DE)
Title: Preventing swinging of filter plates during movement - by guides attached to alternating long and short suspension arms
Inventor: HOEFER KARL ING GRAD
IPC: B01D25/172
Filed: 1979-06-13
Abstract: In a filter press support with parallel guide beams along which move guides carrying suspension arms for the filter plates, the alternating plates have long and short lateral suspension arms. All the short arms are connected to guide shoes or rollers which move in an outer track along the guide beams, and all the longer arms are connected to similar shoes or rollers in an inside track in the beam. Each guide is longer than the thickness of its corresp. filter plate. Each plate has a long arm at one side of the centre line and a short arm at the other side. In some cases a third still longer arm may be used, with a further track. The plates are prevented from swinging when being advanced, separated, etc.. and since the suspension arms are vertical and short, in simpler manner than with known filters employing inclined suspension arms.
Patent DE-2924118-A1 (DE)
Title: Bottom pour sliding stopper for pouring ladles - where spring pressure on overhanging end of sliding stopper plate is released when stopper is closed
Inventor: HANNES HEINZ-DIETER
IPC: B22D41/40
Filed: 1979-06-15
Abstract: Underneath the ladle is a stationary plate (2), and then a mobile stopper plate (4) located in a sliding frame. Both plates (2,4) are made of refractory material. The sliding frame contains springs, which press plate (4) upwards against plate (2). The springs rest on a bedplate (16) which has sloping surfaces, so that when the stopper is closed and part of plate (4) projects beyond plate (2), the spring pressure is released on the projecting end of plate (4). The springs mounted near both edges of plate (4) pref. rest on plates (15a,15b) which slide along the sloping surfaces of bedplate (16). In conventional stoppers, the springs exert a bending moment on plate (4) along the edges of plate (2) after closure; this force can break plate (4). The invention eliminates this problem.

Title: Preparation of cells on microscope slides - by filtering from body fluids with a plastic membrane filter, fixing, rendering the membrane filter transparent, and staining
Inventor: AEIKENS BERNHARD DR MED
IPC: G01N33/483
Filed: 1979-07-17
Abstract: New process is claimed for obtaining and evaluating cell prepns. from liq. media (esp. urine and body fluids) for testing for indications of tumours, in which the cells are applied to a transparent microscope slide, fixed, stained, and examined and evaluated. The liq. medium is filtered by means of a plastic porous membrane filter having a pore size such as to retain the cells under investigation. The cells are simultaneously or subsequently fixed on the membrane filter, and the membrane filter is converted into a transparent state before or after it is placed on the microscope slide. The cells are stained using one or more dye baths after the membrane filter has been converted into the transparent state. New appts. for carrying out the above process is a prepn. set comprising (a) a disposable syringe with an attachable filter unit with a porous plastic membrane filter; (b) a fixing agent for preserving organic cells; (c) a chemical liq. to convert the membrane filter into transparent state; (d) a chemical dye bath for staining the organic cells; and (e) a transparent slide to take the membrane filter.

Title: Bulletproof laminated fabric for vests etc. - utilising aramid fibres to form relatively thin and lightweight garments
Inventor: STAATS HORST ING GRAD
IPC: F41H5/04
Filed: 1979-07-31
Abstract: Fabrics woven or knitted from polyaramide fibres, in layers which are offset to each other, are fastened together along their length to form a sheet material giving protection against penetration by a bullet. The layers may be glued or rivetted together and the fastening points are common to all the layers. The layers may be of different material with inserts between them of material capable of obstructing the passage of a bullet. The laminate is exclusively of textile material, and gives a high degree of protection against bullets and shrapnel without an intolerably large thickness or weight.

Title: Flame battery for pig carcass bristle removal - with linked combustion chambers for each gas burner
Inventor: KAUFMANN SIEGFRIED ING GRAD
IPC: A22B5/08
Filed: 1979-08-11
Abstract: A flame battery for the final stage of the removal of bristles from pig carcasses is connected to a common gas supply. Each burner has its own combustion chamber which is linked to that of the adjoining burners by short pieces of pipe. Both ends of such a pipe penetrate inside the combustion chambers; one end is cut off square but the other is cut obliquely, with the end facing the arriving gas like a spoon. This creates a cross flow from chamber to chamber and prevents the extinction of some of the burners which would have to be constantly observed and re-ignited by blow lamp.
